Each product has a life cycle and steels, due to its peculiar properties and characteristics, show a cycle life above 15 years. The steels types for civil construction in Brazil was developed 60 years ago for anothers uses, like mechanical construction,automotive industry and shipping. In order to enlarge and consolidate the civil construction market, Usiminas has developed, in the last years, the steels USI SAC 300 e USI SAC 350. These steels grades have a extra atmosphere corrosion resistance and low Cu addition, and substituted the traditionals weathering steels Usiminas USI-SAC 41 and USI SAC 50, produced since 70s.This study compare the corrosion resistance performances of the new steel USI SAC 300 and the traditional weathering steel USI-SAC 41, using physicals and chemicals tests
